Description

Technical Field

[0001] This utility model relates to the field of product inspection technology, and in particular to an internal width and weight detection device. Background Technology

[0002] Product inspection is an important part of product quality assurance. Traditional measurement uses measuring tools such as calipers, micrometers, and thickness gauges. Product weight is mostly weighed with electronic scales, and relevant measurement data is recorded manually. With the development of technology, intelligent measurement, such as infrared sensing, CT scanning, weight sensors, and automated data recording, is increasingly being widely used in testing methods and equipment.

[0003] For bicycle frame forks, it is necessary to measure the inner width and weight of the fork. The traditional method of inspection and recording involves manually measuring the inner width and weight of the fork separately, and then manually entering the measurement data into an electronic document for archiving.

[0029] Product inspection is an important part of product quality assurance. Traditional measurement uses measuring tools such as calipers, micrometers, and thickness gauges. Product weight is mostly weighed with electronic scales, and relevant measurement data is recorded manually. With the development of technology, intelligent measurement, such as infrared sensing, CT scanning, weight sensors, and automated data recording, is increasingly being widely used in testing methods and equipment.

[0030] For bicycle frame forks, it is necessary to measure the inner width and weight of the fork. The traditional method of inspection and recording involves manually measuring the inner width and weight of the fork separately, and then manually entering the measurement data into an electronic document for archiving. This measurement and recording method is not only inaccurate, but also inefficient in terms of inspection and recording.

[0031] Therefore, there is an urgent need for a new type of inner width and weight detection equipment to solve the problem that traditional measurement methods require manual measurement of the inner width and weight of the fork, and manual input of the data into electronic documents for archiving.

[0032] Based on this, the present invention proposes an inner width and weight detection device.

[0033] Please see Figure 1 and Figure 2In one embodiment of this utility model, the inner width and weight detection device 1 is applied to a front fork 2. The front fork includes a fork crown 21, a left pawl end tube shaft 22, and a right pawl end tube shaft 23. The fork crown 21 is connected to the left pawl end tube shaft 22 and the right pawl end tube shaft 23 respectively. The inner width and weight detection device 1 includes a communication module 11, a fixing fixture 12, a weighing device 13, and a distance measuring device 14. The fixing fixture 12 has a snap-fit ​​part 121 for snapping into the fork crown 21. The weighing device 13 is equipped with... The weighing device 13 is placed at the bottom of the fixed fixture 12 and is connected to the communication module 11. The weighing device 13 is used to weigh the fixed fixture 12 and the front fork 2 and send the weight measurement value to the communication module 11. The distance measuring device 14 is connected to the communication module 11. The distance measuring device 14 is used to measure the inner width between the left hook end cylinder shaft 22 and the right hook end cylinder shaft 23 and send the inner width measurement value to the communication module 11. The communication module 11 is used to receive and save the weight measurement value and the inner width measurement value.

[0034] The technical solution of this utility model employs an internal width and weight detection device 1, which includes a communication module 11, a fixing fixture 12, a weighing device 13, and a distance measuring device 14. By utilizing the locking part 121 of the fixing fixture 12, the fork crown 21 of the front fork 2 is locked in place, achieving relative positioning of the front fork 2. This allows the weighing device 13 and the distance measuring device 14 to accurately measure the positioned front fork 2. The weighing device 13 is located at the bottom of the fixing fixture 12 and can monitor the fixing fixture 12 and the front fork 2. The weight is measured. Since the weighing device 13 is connected to the communication module 11, after the weight measurement value is obtained, the weighing device 13 can send the weight measurement value to the communication module 11 so that the communication module 11 can save it. The distance measuring device 14 can measure the inner width between the left hook end cylinder shaft 22 and the right hook end cylinder shaft 23. Since the distance measuring device 14 is connected to the communication module 11, after the inner width measurement value is obtained, the distance measuring device 14 can send the inner width measurement value to the communication module 11 so that the communication module 11 can save it.

[0035] The internal width and weight detection device 1 of this utility model can locate the front fork 2 to improve the measurement accuracy. It uses a weighing device 13 and a distance measuring device 14 to automatically measure the weight and internal width of the front fork 2. After the measurement is completed, the weight measurement value and the internal width measurement value are automatically sent to the communication module 11 for storage. This realizes efficient measurement and recording operations and improves detection and recording efficiency.

[0036] It should be noted that this weighing device can employ various types of weighing equipment, such as electronic scales and weight sensors. It has an internal communication unit capable of communicating with the communication module 11. The communication method can be set to conventional forms such as Bluetooth, WiFi, and 4G, which will not be elaborated upon here. The operation of sending the measurement result to the external communication module 11 (such as a mobile phone or signal receiver) via the communication unit after obtaining a stable weight measurement is a standard function of existing electronic scales and other measuring devices, and this function does not require modification to the computer program. Furthermore, since the measuring device measures the sum of the weights of the fixed fixture 12 and the front fork 2, and the weight of the fixed fixture 12 is fixed and can be pre-measured (this weight can be stored locally on the measuring device), the final weight measurement of the front fork 2 obtained by the measuring device is the difference between the total weight and the weight of the fixed fixture 12. It should be noted that since the weight of the fixed fixture 12 can be measured manually in advance and stored in the weighing device 13, and the calculation of the weight measurement value is only a simple difference between the total weight and the weight of the fixed fixture 12, the implementation of this measurement function does not involve any improvement to the computer program. Operators can achieve this measurement function by modifying the parameters according to the conventional weight measurement program.

[0037] Furthermore, the distance measuring device 14 can employ electronic distance measuring equipment such as an optical displacement sensor, which has an internal communication unit capable of communicating with the communication module 11. The communication method can be set to conventional communication forms such as Bluetooth, WiFi, and 4G, which will not be elaborated here. The operation of the distance measuring device 14 sending the measurement result to the external communication module 11 (such as a mobile phone or signal receiver) through the communication unit after obtaining a stable inner width measurement value is a conventional function of existing electronic distance measuring equipment, and this function does not require modification of the computer program.

[0038] Additionally, the communication module 11 may include at least a communication unit and a computer-readable storage medium, with the communication unit electrically connected to the computer-readable storage medium. After the communication unit receives either the weight measurement value or the inner width measurement value, the communication module 11 saves the measurement result locally. The function of the communication module 11 in receiving and saving information is a conventional function of existing communication devices (such as signal receivers, communication units, computers, etc.), and its implementation does not require modification of the computer program.

[0039] Please see Figure 1 and Figure 2In this embodiment of the present invention, there is an angle between the axial direction of the fork crown 21 and the extension direction of the left hook end cylinder shaft 22 and the extension direction of the right hook end cylinder shaft 23; the fixing fixture 12 includes a base 122, a height adjusting member 123 and a locking part 121, the locking part 121 is disposed on the base 122, the base 122 is provided with a track groove 1221, and the height adjusting member 123 is slidably disposed in the track groove 1221; the weighing device 13 is disposed at the bottom of the base 122; the top of the height adjusting member 123 is used to support the left hook end cylinder shaft 22 and the right hook end cylinder shaft 23; the height adjusting member 123 is used to move along the track groove 1221 to adjust the contact part between the top of the height adjusting member 123 and the left hook end cylinder shaft 22 and the right hook end cylinder shaft 23.

[0040] In this embodiment, since there is an angle between the axial direction of the fork crown 21 and the extension direction of the left hook end cylinder shaft 22 and the extension direction of the right hook end cylinder shaft 23, the fixing fixture 12 includes a base 122, a height adjustment member 123 and a locking part 121. After the locking part 121 locks the fork crown 21 of the fork 2, the top of the height adjustment member 123 supports the left hook end cylinder shaft 22 and the right hook end cylinder shaft 23. By moving the height adjustment member 123 along the track groove 1221, the contact points between the top of the height adjustment member 123 and the left hook end cylinder shaft 22 and the right hook end cylinder shaft 23 are changed, thereby adjusting the height difference between the left hook end cylinder shaft 22, the right hook end cylinder shaft 23 and the base 122. This adjusts the height of the left hook end cylinder shaft 22 and the right hook end cylinder shaft 23 to a position that matches the measuring part of the distance measuring device 14, which helps to reduce the measurement error of the distance measuring device 14 and improve the accuracy of the inner width measurement.

[0041] In this embodiment of the invention, the top of the height adjusting member 123 is configured as an arc-shaped structure, which abuts against the left hook end cylinder shaft 22 and the right hook end cylinder shaft 23. In this embodiment, by configuring the top of the height adjusting member 123 as an arc-shaped structure, the sliding friction between the height adjusting member 123 and the left hook end cylinder shaft 22 and the right hook end cylinder shaft 23 is reduced during the movement of the height adjusting member 123 along the track groove 1221. This reduces wear on the left hook end cylinder shaft 22 and the right hook end cylinder shaft 23 and also reduces the resistance encountered when moving the height adjusting member 123.

[0042] Please see Figure 3 In an embodiment of this utility model, a plurality of first notches 1222 are provided on the base 122. The provision of the first notches 1222 can effectively reduce the weight of the base 122 and prevent the weighing device 13 from bearing too much weight, which would exceed the measuring range of the weighing device 13.

[0043] Please see Figure 1 and Figure 3In an embodiment of this utility model, the distance measuring device 14 includes an optical displacement sensor 141 and an optical refractive element 142. The optical refractive element 142 is disposed between the left claw end cylinder shaft 22 and the right claw end cylinder shaft 23. The optical displacement sensor 141 is disposed facing the optical refractive element 142. The optical displacement sensor 141 is communicatively connected to the communication module 11. The optical refractive element 142 is used to refract the measuring beam emitted by the optical displacement sensor 141 to the opposite inner surfaces of the left claw end cylinder shaft 22 and the right claw end cylinder shaft 23.

[0044] In this embodiment, by employing an optical displacement sensor 141 and an optical refractive element 142, the propagation path of the measurement beam emitted by the optical displacement sensor 141 is changed by the optical refractive element 142, thereby freeing up the placement position of the optical displacement sensor 141. By placing the optical refractive element 142 between the left hook end cylinder shaft 22 and the right hook end cylinder shaft 23, and setting the optical displacement sensor 141 toward the optical refractive element 142, it is possible to achieve the effect of optical measurement of the inner width of the front fork 2 through the refraction of the beam by the optical refractive element 142 without placing the optical displacement sensor 141 between the left hook end cylinder shaft 22 and the right hook end cylinder shaft 23.

[0045] Please see Figure 1 and Figure 3 In an embodiment of this utility model, the optical displacement sensor 141 has a first sensing end 1411 and a second sensing end 1412. The optical refractive element 142 includes a first refractive part 1421 and a second refractive part 1422. The first refractive part 1421 is connected to the second refractive part 1422. The first sensing end 1411 is disposed toward the first refractive part 1421, and the first refractive part 1421 is inclined toward the inner side of the left claw end cylinder shaft 22. The first refractive part 1421 is used to refract the measurement beam emitted by the first sensing end 1411 to the inner side of the left claw end cylinder shaft 22. The second sensing end 1412 is disposed toward the second refractive part 1422, and the second refractive part 1422 is inclined toward the inner side of the right claw end cylinder shaft 23. The second refractive part 1422 is used to refract the measurement beam emitted by the second sensing end 1412 to the inner side of the right claw end cylinder shaft 23.

[0046] In this embodiment, by including a first refractive part 1421 and a second refractive part 1422 in the optical refractive element 142, the first refractive part 1421 refracts the measurement beam from the first sensing end 1411 of the optical displacement sensor 141, so that the measurement beam from the first sensing end 1411 can be refracted to the inner surface of the left hook end cylinder shaft 22, thereby measuring the distance between the first refractive part 1421 and the inner surface of the left hook end cylinder shaft 22, which can be defined as the first distance; and the second refractive part 1422 refracts the measurement beam from the second sensing end 1412 of the optical displacement sensor 141. To refract the measuring beam from the second sensing end 1412 onto the inner surface of the right hook end cylinder shaft 23, the distance between the second refractive part 1422 and the inner surface of the right hook end cylinder shaft 23 is measured, which can be defined as the second distance. Since the first refractive part 1421 and the second refractive part 1422 are connected, the preset distance between the first refractive part 1421 and the second refractive part 1422 is fixed and can be measured in advance. This preset distance can be stored in advance in the optical displacement sensor 141. The final measured inner width value is the sum of the first distance, the second distance, and the preset distance. It should be noted that since the preset distance can be manually measured in advance and stored in the optical displacement sensor 141, and the calculation of the inner width value is only a simple sum of the first distance, the second distance, and the preset distance, the implementation of this measurement function does not involve any improvement to the computer program. The operator can achieve this measurement function by modifying the parameters according to the measurement program of the conventional optical displacement sensor 141.

[0047] As an optional implementation, the first refractive part 1421 is configured as a prism; and / or, the second refractive part 1422 is configured as a prism. Thus, since a prism has excellent optical refraction effects, configuring the first refractive part 1421 and the second refractive part 1422 as prisms effectively refracts the measurement beam, reducing the dissipation of the measurement beam during refraction. Furthermore, as an optional implementation, the optical displacement sensor 141 is configured as a laser displacement sensor. The laser measurement beam emitted by the laser displacement sensor has high collimation, is not easily diffused, and is suitable for high-precision measurement; therefore, it is used in this optical displacement sensor 141.

[0048] Please see Figure 1 and Figure 2 In an embodiment of this utility model, the inner width and weight detection device 1 further includes a table 15, a distance measuring device 14 is disposed on the table 15, the table 15 has a top plate 151, the top plate 151 has a second notch, the fixing fixture 12 is placed in the second notch, the bottom of the top plate 151 is provided with a first drawer cabinet 152, the first drawer cabinet 152 is placed with a weighing device 13, and the weighing end of the weighing device 13 abuts against the fixing fixture 12.

[0049] In this embodiment, the internal width and weight detection device 1 also includes a table 15, which provides storage and holding functions. The top plate 151 of the table 15 has a second notch, allowing the fixing fixture 12 to be partially recessed and placed in the second notch. The weighing device 13, placed inside the first drawer cabinet 152, provides support and abutment for the fixing fixture 12, thereby reducing the space occupied by the fixing fixture 12 above the top plate 151. Furthermore, since the fixing fixture 12 is entirely supported by the weighing device 13, the weighing device 13 can measure the weight of the fixing fixture 12 and the front fork 2 it is attached to, thus achieving the effect of measuring the weight of the front fork 2. In addition, other items or components can be placed inside the top plate 151 of the table 15 and the first drawer cabinet 152. For example, the distance measuring device 14 can be placed on the top plate 151, while the front fork 2, which is attached to the fixing fixture 12, can protrude from the top plate 151 so that the distance measuring device can measure the internal width of the front fork 2.

[0050] As an optional implementation, the first drawer cabinet 152 may be provided with a connecting part. The connecting part can be connected to the bottom of the top plate 151 through various connection methods such as fasteners and welding, which will not be described in detail here.

[0051] Please see Figure 1 and Figure 2 In an embodiment of this utility model, the table 15 further includes a left side panel 153, a right side panel 154, and a horizontal panel 155. The top panel 151 is connected to the top of the left side panel 153 and the top of the right side panel 154, respectively. The horizontal panel 155 is connected to the left side panel 153 and the right side panel 154, respectively. The horizontal panel 155 is located below the top panel 151. The top panel 151, the horizontal panel 155, the left side panel 153, and the right side panel 154 form a second drawer cabinet 156. The communication module 11 is located in the second drawer cabinet 156; or, the first drawer cabinet 152 also contains a communication module 11.

[0052] In this embodiment, two methods for placing the communication module 11 are provided. One method is that the table 15 can be arranged into a second drawer cabinet 156 by the top plate 151, the horizontal plate 155, the left side plate 153, and the right side plate 154, so that the communication module 11 can be placed in the second drawer cabinet 156. This solution can realize the partitioned placement of the weighing device 13 and the communication module 11, and avoid interference caused by the weighing device 13 and the communication module 11 being too close. The other method is to place the communication module 11 directly in the first drawer cabinet 152, so that a single drawer cabinet can complete the storage effect of the communication module 11 and the weighing device 13.

[0053] In this embodiment of the invention, the weighing end of the weighing device 13 is connected to the fixing fixture 12. This avoids measurement errors caused by mechanical deformation factors such as misalignment between the weighing end and the fixing fixture 12. Alternatively, the weighing end of the weighing device 13 is provided with a threaded hole, and the fixing fixture 12 is provided with a through hole. The fixing fixture 12 is threadedly connected to the weighing end of the weighing device 13 via threaded fasteners to achieve a stable and reliable connection.

[0054] Please see Figure 1 In an embodiment of this utility model, the inner width and weight detection device 1 further includes a computer 16, which is connected to the communication module 11. The computer 16 is used to receive and display the weight measurement value and the inner width measurement value.

[0055] In this embodiment, by connecting the computer 16 to the communication module 11, the computer 16 receives and displays the weight and inner width measurements, allowing the operator to intuitively understand the weight and inner width measurements of the fork 2. It should be noted that the communication module 11 sending parameters to the computer 16, and the computer 16 receiving and displaying the parameters, are standard functions in existing computer programs. Setting the specific parameters sent as the weight and inner width measurements of the fork 2 only involves adjusting the parameter types, and this adjustment does not involve any improvement to the computer program.

[0056] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
